Definitions

  • the conventional drilling devices for producing undercuts are complex and, due to the design, must use a separate drill holder into which the drill can be screwed.
  • the guide sleeve preferably has a flange facing the collar with an inwardly curved contact surface, which represents a pivot bearing for the spherical collar. The pivoting movement for rubbing out the undercut is thereby facilitated.
  • the drill 1 shown in FIG. 1 consists of a drill shaft 2, which is divided into a front section 2a provided with drilling dust grooves 3 and a rear section 2b.
  • the shaft section 2b can be clamped into a chuck of an impact drill or the like, not shown here.
  • the tapered inner bore 22 limits the pivoting movement of the drill shaft within the guide sleeve 18, which limits the maximum pivoting movement, so that reproducible undercuts can be produced.
